FRUIT-BRUSHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 440,677, dated November 18, 1890.

Application iiled January 10, 1889. Serial No. 296,023. (No model.)

To all whom t may concern.-

Be it known that we, HUMPHREY J. WIL- LIAMs and SAMUEL CAMPBELL WARNER, of New York Mills, Oneida county, New York, have invented a certain new and useful Improvement in Fruit-Brushing Machines; and we hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

Our invention relates to a brushing-Inachine for cleaning the surfaces of oranges or similar fruit; and it consists in the mechanism hereinafter pointed out and claimed.

In the drawings, Figure l represents a side elevation of our machine. Fig. 2 represents an end View taken from the left of Fig. 1. Fig. 3 represents a vertical section on line A B of Fig. 1. Fig. 4L represents a plan View of our machine with the hopper removed. Fig. .5 represents a portion of the adjusting mechanism, taken from Fig. 2 with the gears removed; and Fig. 6 represents details of construction of our feeding device.

In the drawings similar figures of reference refer to corresponding parts throughout the several figures.

We provide frame 1 of suitable construction for supporting the working mechanism, hereinafter more fully described.

In the upper portion of the frame we provide inclined hopper 2, having an inclined floor and sides with opening 3, Fig. 3, at the lowest point of the hopper so arranged that the fruit to be operated upon will by gravity move down to and through opening 3 at the lowest point in the hopper. Any other suitable hopper may be provided through which the fruit may be supplied to the machine.

In opening 3 in the hopper we provide what we term a feeding device, which feeds one article at a time and operates as follows: Roller 4, Figs. 3 and 6, is pivoted in the hopper at opening 3, and is provided with a semicircular'groove or recess for receiving vand carrying a single article of fruit. Roller .4: 5o

nects at its opposite end to a crank-pin 11 on sprocket-wheel 10. The unequal pivoting of the connecting-rod with disk 7 and sprocketwheel 10 produces a rocking motion of roller 4 with each revolution of sprocket-wheel 10. The roller 4. is rocked from the position shown in Fig. 3 and in broken lines in Fig. 6, in which it receives the fruit from the hopper, to that shown in full lines in the left-hand portion of Fig. 6, when it discharges the fruit to the brush, the fruit passing over the roller. Movement is imparted to the roller et through the mechanism already described, and link belt 12, Fig. 2, running over sprocket-wheel 13, rigidly connected to sprocket-wheel13 and sprocket- wheels 10 and 50. Both of these sprocketwheels 13 and 13 are mounted loosely on the shaft 36, Fig. 4, and are driven by crank 1-1 or othersuitable power. Sprocket-wheel 10 is provided with two sprocketed bearing-surfaces, as shown in Fig. 4:. The belt which drives the sprocket-wheel 10 runs over the outer bearing surface. Double sprocket-wheel 10 runs on a suitable bearing fixed in the frame.

Underneath the feeding device already described we provide rotating brush 15, Figs. 3 and L1, mounted on bearings at each end in the frame. rEhe brush is mounted on shaft 22, Fig. 2, which preferably passes through the brush and runs in bearings in the frame, and on one end of the shaft we provide sprocket-wheel 23, Fig. 2, rigidly secured thereto. The brushis driven by endless belt 24, running on sprocket-wheels 13 and 23, so

as to impart the required rotary motion tothe brush.

Mounted on suitable bearings in. the frame we provide on each side of the brush carriers 16 and 17, Figs. 3 and 4, each of which car` riers is provided with a spiral projection, preferably composed of independent projections or pins, although a continuous spiral projection may be provided. We prefer the independent projections, as they more Aefficiently rotate the fruit against the brush and furnish less place of lodgment for dirt. The projections on the carriers are provided for carrying each article to be operated on along tracks 19 and 20, Figs. 3, 4, and 5, between the brush and carriers. In the machine, as shown, the fruit moves from the left to the right hand end of the machine, and is then returned from the right to the left, as hereinafter explained. Tracks 19 and 20, between the carriers and the brush on which the fruit moves, are adjustable with reference to the brush and carriers by being mounted upon swinging arms, as hereinafter set forth. On the surface of tracks 19 and 20, on which the fruit moves, may be provided projections 2l, which serve to change the position of the fruit moving on the tracks with more certainty and present all its sides to the brush and prevent it from sliding along the tracks and not presenting all its surfaces to the brush. A proj ection 21 may also be provided, which serves to raise the fruit onto the connecting-track passage-way or chute 57 whereby it is transferred from track 19 to track 2O upon the opposite side of the brush. It is evident that projections 21 and 21 are not essential, but only expedient. The chute 57 is inclined from the track 19 to track 20, and the fruit rolls across by its own gravity. The inclined projection 21a is provided to facilitate thel fruit more readily getting onto the inclined chute 57, and so the chute will pass above the shaft which carries the brush. It is evident that the construction could be varied in several particulars', so that the inclined projection 21 would not be necessary or even expedient.

The tracks and carriers are adjustable with reference to each other and to their location to the brush by the use of the following mechanism: The carriers are journaled at each end, as shown at 25 and 26 of Fig. 5, in swinging arms 27 and 28, provided at each end of the frame and pivoted thereto at 29 and 30, and these arms are connected at their upper ends at 31 and 32 by connecting-links 33 and 34 to toothed wheel 35 at points 37 and 38. l/Vheel 35 is secured to shaft 36, Figs. 4 and 5, which passes through the machine and has disk 36a connected at the opposite end thereof, to which disk is connected a similar system of swinging arms and connecting-links to that already described, so

-that when the toothed Wheel 35 on the shaft 36 is operated by the lever 37a, Fig. 5, the carriers are adjusted outorin from the brush to accommodate articles of different size. Tracks 19 and 20 are mounted at each end in swinging arms 39 and 40, pivoted to the frame at- 41 and 42, respectively, their upper ends being connected or pivoted at 43 and 44 to suitable connecting-rods, which pass to Wheel 35, and are pivoted thereto at 45 and46, respectively, the pivotal points 45 and 46 being'preferably nearer the center of the wheel than the pivotal points 37 and 38 of the links connectlng with the arms carrying the bearings of the carriers. A similar system of arms carrying the other ends of the tracks is provided upon the other end of the machine and having substantially the same connections. When the carriers and tracks are adjusted in the position desired and suitable to the size of the fruit being operated on. they are held by pawl 47, pivoted to the frame at 48, the pawl engaging teeth 49 on the periphery of the toothwheel 35. Power is transmitted to carrier 16 by endless belt 54, Fig. 2, running over the inner bearing-surface of double sprocketwheel 10 and sprocket-wheel 55,--rigidly held to the end of the shaft of carrier 16, and power is transmitted to carrier 17 by the belt l2, passing over the sprocket 50, mounted on a suitable bearing in the frame, the sprocketwheel 50 being rigidly connected to gear-wheel 5l, which meshes into and drives gear-Wheel 52. Gear-wheel 52 is rigidly ii'xed to the end of the shaft of carrier 17. On the end of the shaft carrying the brush we mount balancewheel 59, Fig. 1, for regulating the speed of the machine when the same is operated by crank 14 or other suitable power. At the right-hand end of carrier 16 and secured thereto we provide projections 58 58, Fig. 3, for moving the fruit onto the inclined chute 57, Fig. 4, which chute conducts the fruit to the carrier and track upon the opposite side of the brush, the direction of the movement of the fruit along the tracks 19 and 20 being shown bv the arrows. At t-he left-hand end of carrier 17, Fig. 4, we provide the projecting flange a, Fig. 4, extending around the carrier, which operates to stop the movement of the fruit when it reaches the flange, and in the same end of the carrier we provide a projecting lifter 60, rigidly secured to the carrier and projecting beyond the periphery thereof, so that when the fruit is brought down against iange @by the movement of the carrier projecting lifter 60 engages' the fruit on the under side and carries it over the carrier and discharges it on the inclined chute 61, Figs. 3 and 4, by which it is discharged from the machine.

Various modifications from the mechanism already described will readily suggest them'- selves, which various modifications are within the scope of our invention and the equivalents of our construction.

What we claim as new, and desire to secure by Letters Pat-ent, is

1. In a brushing-machine, the combination of a rotary brush, the carrier provided with a spiral projection thereon, the swinging arms in which the carrier is mounted, means for adjusting them with reference to the brush, and the track between the brush and the carrier.
